    Feb 14, 2012Opening a completely isolated SF6 breaker with very little or no SF6 gas (as if it were in a testing lab) would pose no threat to the health of the breaker. There is no auto-trip feature.

    SF 6 gas is extremely stable and inert, and its density is five times that of air. It has high thermal conductivity better than that of air and assists in better cooling current carrying parts. SF 6 gas is strongly electronegative, which means the free electrons are easily removed from discharge by the formation of negative ions.
